The Launch Services Program (LSP) is currently awarding new contracts under the NASA Launch Services (NLS) II Contract.[5] Once a year, new launch vehicles can be on (or off) ramped onto the contract.[6] The following vehicles are attached to the NLS II Contract.

• Antares [7] – Orbital Sciences Corporation (OSC)
• Atlas V – United Launch Alliance (ULA)
• Delta IV Heavy – United Launch Alliance (ULA)
• Falcon 9 – SpaceX
• Falcon Heavy – SpaceX
• Pegasus XL – Orbital Sciences Corporation (OSC)
• Taurus XL – Orbital Sciences Corporation (OSC)

NASA has specific policies governing launch services.[8] LSP Flight Design provides general information regarding the launch vehicle performance available via existing NASA contracts.[9] This information is all available on publicly available websites.

NASA uses a certification system for rockets launched by its contractors, and for validation purposes it requires the certification process to be "instrumented to provide design verification and flight performance data", with post-flight operations, anomaly resolution process, and a flight margin verification process, with 80% predicted design reliability at 95% confidence.[10]

In addition to providing end-to-end launch services, LSP also offers Advisory Services.[12] This "is a consulting service to government and commercial organizations, providing mission management, overall systems engineering and/or specific discipline expertise; e.g. mission assurance, flight design, systems safety, etc., as requested." This non-traditional service allows LSP to "expand its customer base and assist these customers in maximizing their mission success by using NASA LSP's unique expertise." The four general categories of advisory services are:

• SMART (Supplemental Mission Advisory and Risk Team)
• Design and Development
• Independent Verification and Validation (IV&V)
• Independent Review Teams (IRT)

LSP also works with the United States Space Force (USSF),[13] via coordination by the LVCs. For launches at Cape Canaveral Space Force Station (CCSFS) and Vandenberg Air Force Base (VAFB), the 45th Space Wing and 30th Space Wing[14] commanders, respectively, are the Launch Decision Authority.[15]

For launches from CCSFS, guardians, Space Force civilians and contractors from throughout the 45th Space Wing provided vital support, including weather forecasts, launch and range operations, security, safety, medical and public affairs. The wing also provided its vast network of radar, telemetry, and communications instrumentation to facilitate a safe launch on the Eastern Range.[16][17][18][19] Among work done by the Space Force is Mission Flight Control, which ensures public safety during launch.[20][21][22][23]

The weather conditions acceptable for launch vary by rocket and even the configurations of the rocket.[24][25][26][27][28] Prior to liftoff are multiple sets of acceptable weather conditions that depend on the state of the rocket, particularly where the rocket is in the fuel loading process.

The engineers at NASA's Launch Services Program are rocket experts.[65] Below are some examples of jobs within LSP that NASA has written articles on.

• Flight Design analysts work on the intended course, or trajectory, of the rocket.[66][67]
• Telemetry engineers get tracking stations to cover all the mandatory portions of flight.[66][68][69] Analysts from many disciplines review this data post-flight.
• Weather Forecasters Balance Experience with Technology
• The Failure Analysis and Materials Evaluation Lab assists the program by examining failures and figuring out what went wrong [70]

The Launch Services Program operates Hangar AE on the Cape Canaveral Space Force Station. It is LSP's Launch Communications Center.[71] For Florida launches, many of the primary LSP engineers on console are in Hangar AE. For launches from California and other launch sites, many of support LSP engineers are on console there. Launch vehicle contractors and spacecraft engineers will often operate out of the Hangar also. It gathers telemetry for rocket launches beyond those worked by LSP.

Members of the Launch Services Program perform research relating to launching unmanned NASA spacecraft.[72] Research topics include (partial list):

• Collision Avoidance (COLA)[73][74]
• Upper-level Winds on Day-of-Launch;[75][76][77][78] collaborations with groups such as:
  • NASA Kennedy Space Center's Applied Meteorology Unit (AMU)
  • 45th Space Wing
• Slosh Fluid Dynamics [79]

SPHERES-Slosh

SPHERES-Slosh Experiment will be performed on the SPHERES Testbed on the International Space Station. The experiment launched on the Cygnus capsule going to the ISS via Orbital Sciences Corporation Commercial Resupply Services Orb-1 mission on an Antares on 2014.01.09.[80][81][82][83] The Cygnus arrived at the ISS on 2014.01.12 and will spend five weeks unloading the cargo.[84]

The SPHERES-Slosh investigation uses small robotic satellites on the International Space Station to examine how liquids move around inside containers in microgravity. A water bottle's contents slosh around differently in space than on Earth, but the physics of liquid motion in microgravity are not well understood, which affects computer simulations of liquid rocket fuel behavior. LSP leads a team that includes Florida Institute of Technology[85][86][87] and Massachusetts Institute of Technology. The research is sponsored by the Game Changing Development (GCD) program (within NASA Technology Demonstration Office (TDO)'s Space Technology Mission Directorate).[88] [89][90] [91][92] [93]

The experiment is a water tank with cameras and sensors that will be mounted between two SPHERES satellites inside the ISS. During testing, the SPHERES will move to purposely agitate the water and cause the fluid inside to slosh around, like it might in a rocket or spacecraft tank during flight. The data collected will be one of a kind. Three initial tests are expected to happen with the first couple months of launch.

"The current inability to accurately predict fuel and oxidizer behavior can result in unnecessary caution, requiring extra propellant to be added along with additional helium for tank pressurization. A better understanding of fluid slosh could not only decrease this uncertainty, but increase efficiency, reduce costs and allow additional payloads to be launched."[94] Understanding from this experiment could help improve design/operations of rocket tanks and control systems.

NASA's Brandon Marsell, co-principal investigator on the Slosh Project: "Modern computer models try to predict how liquid moves inside a propellant tank. Now that rockets are bigger and are going farther, we need more precise data. Most of the models we have were validated under 1 g conditions on Earth. None have been validated in the surface tension-dominated microgravity environment of space." (via Langley Research Center article[95])

Slosh is the first project on the ISS to use 3D printed materials for its experiment. NASA's Jacob Roth, project manager on the Slosh Project, on the first science session: "The results from our first checkout run are proving interesting. While not too unexpected, the bubble/liquid interaction behavior appears to be exhibiting a slightly different interaction than current models predict." The team will be altering the tests for the second session based on the preliminary results.[96]

The 2008-2010 slosh related tests on SPHERES were performed with a single SPHERES spacecraft and, in some cases, the addition of a battery pack Velcroed on to the SPHERES spacecraft. These tests were to better understand the physical properties of the SPHERES spacecraft, notably the mass properties, prior adding any tanks to the system.[97] Some of the tests also attempted to excite and then sense slosh within the SPHERES CO2 tank. Florida Tech designed the slosh experiments for Test Sessions 18/20/24/25.

CRYOTE
The Cryogenic Orbital Testbed (CRYOTE) is a collaboration between NASA and commercial companies to develop an orbital testbed that will demonstrate cryogenic fluid management technologies in space environments. "The testbed provides an in-space environment in which the fluid transfer, handling, and storage of liquid hydrogen (LH2) and/or liquid oxygen (LO2) can be demonstrated."[112][113][114]

The research is funded by the NASA Innovative Partnership Program (IPP) in the Office of the Chief Technologist. "The partners involved in the development of this system include United Launch Alliance (ULA), Sierra Lobo, Innovative Engineering Solutions (IES), Yetispace, and NASA Glenn Research Center, Kennedy Space Center, and Marshall Space Flight Center." [115]

NASA's Launch Services Program Educational Outreach provides awareness to students, teachers and the public about NASA's exciting spacecraft missions and how the world benefits from them. Distance learning via video conference connects students to LSP experts[116]

The office also coordinates activities and educational booths at events for NASA and the public.[117][118][119][120] The outreach is performed by both members of the LSP Educational Outreach Office and LSP experts throughout the program.

The LSP Educational Outreach Office created the Rocket Science 101 Game. Students can pick a NASA mission, select the right rocket, and build a rocket to send the spacecraft into orbit. There are three different levels for varying ages and it is available for the computer and Apple/Android devices.[121]

NASA and the Launch Services Program are partnering with several universities to launch small research satellites. These small satellites are called CubeSats. CubeSat Launch Initiative (CSLI) provides opportunities for small satellite payloads to fly on rockets planned for upcoming launches. As of February 2015, CSLI has selected 119 spacecraft since 2010.[122]

Educational Launch of Nanosatellites (ELaNa)[123] and is a part of CSLI. ELaNa manifests the CubeSats selected by CSLI onto upcoming rocket launches. CubeSats were first included on the launch of LSP missions in 2011. ELaNa missions are not manifested exclusively on LSP missions; they have been a part of NRO/military launches and ELaNa V will be on an International Space Station resupply launch. ELaNa mission numbers are based on the order they are manifested; due to the nature of launching, the actual launch order differs from the mission numbers.

In 2014, as a part of the White House Maker Initiative, CSLI announced its intention to launch 50 small satellites from 50 states within five years. As of July 2014, there were 21 "rookie states" that had not previously been selected by the CSLI[124]

In October 2015, NASA's LSP, with funding partnered by Earth Science Division of NASA's Science Mission Directorate, "awarded multiple Venture Class Launch Services (VCLS) contracts to provide small satellites (SmallSats) -- also called CubeSats, microsats or nanosatellites -- access to low-Earth orbit." Three companies received $4–7 million firm fixed-price contracts. The intention of the VLCS contracts is to provide alternatives to the current rideshare-type approach for launch of small satellites.[125]

ELaNa Launch History

These two high school STEM teams are sponsored and mentored by NASA's Launch Services Program.

FIRST Robotics Competition Team 1592 (the Bionic Tigers) is out of Cocoa High School (CHS) and Holy Trinity Episcopal Academy. The founding mentors of the team were Analex contractors working for LSP; the team has had NASA LSP engineering mentors ever since 2006.[128]

Merritt Island High School, in partnership with California Polytechnic State University, has a team building a CubeSat as part of Kennedy Space Center's Creating Understanding and Broadening Education through Satellite (CUBES) pilot project.[129] The team's StangSat was accepted by the CubeSat Launch Initiative[130] and launched 25 June 2019 as part of ELaNa XV, via the Space Test Program, on a SpaceX Falcon Heavy rocket.[131]

The satellite, named StangSat after the school's Mustang mascot, will collect data on the amount of shock and vibration experienced by payloads while in orbit.,[132]

On June 15, 2013, the team launched an engineering unit of StangSat on the Prospector-18 rocket;[133] the suborbital flight took off from the Friends of Amateur Rocketry site in California's Mojave Desert.[134] The other satellites on board were Rocket University Broad Initiatives CubeSat, or RUBICS-1 (KSC); PhoneSat (ARC); and CP-9 (CalPoly). Though the parachute deployed early, resulting in a hard landing, all four satellites were able to collect usable data.[135]

The team will be only the second high school to launch a satellite into orbit, after Thomas Jefferson High School for Science and Technology's TJ3Sat in November 2013 (another ELaNa mission).[136]
