In this photo, a spacecraft specialist prepares NASA's InSight spacecraft for thermal vacuum testing in the flight system's "cruise" configuration for its 2016 flight to Mars. The testing simulates conditions of outer space that InSight will experience during its flight. The photo was taken on May 29, 2015, in a clean room of spacecraft assembly and test facilities at Lockheed Martin Space Systems, Denver. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA19812

Crews at NASA’s Marshall Space Flight Center in Huntsville, Alabama, moved and installed the payload adapter that will be used in the Block 1B configuration of the SLS (Space Launch System) rocket from Building 4708, where it was manufactured, into Structural Test Stand 4697 at NASA’s Marshall Space Flight Center on March 13.

This artist's concept illustrates the Module Nova concept - Solid C-3 Basis. From 1960 to 1962, the Marshall Space Flight Center considered the Nova launch vehicle as a means to achieve a marned lunar landing with a direct flight to the Moon. Various configurations of the vehicle were examined. The latest configuration was a five-stage vehicle using eight F-1 engines in the first stage. Although the program was canceled after NASA planners selected the lunar/orbital rendezvous mode, the proposed F-1 engine would eventually be used in the Apollo Program to propel the first stage of the Saturn V launch vehicle.

In this 1962 artist's concept , a proposed Nova rocket, shown at right, is compared to a Saturn C-1, left, and a Saturn C-5, center. The Marshall Space Flight Center directed studies of Nova configuration from 1960 to 1962 as a means of achieving a marned lunar landing with a direct flight to the Moon. Various configurations of the vehicle were examined, the largest being a five-stage vehicle using eight F-1 engines in the first stage. Although the program was effectively cancelled in 1962 when NASA planners selected the lunar-orbital rendezvous mode, the proposed F-1 engine was eventually used to propel the first stage of the Saturn V launch vehicle in the Apollo Program.

Illustration of evolved SLS Block 1B Crew variant in flight. This configuration of the rocket, with the Exploration Upper Stage, will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and heavy cargo on a precise trajectory to the Moon. The evolution of the rocket to SLS Block 1B configuration with EUS enables SLS to launch 40% more cargo to the Moon along with the crew. Manufacturing both the core stage and Exploration Upper Stage is a collaborative effort between NASA and Boeing, the lead contractor for EUS and the SLS core stage. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. The SLS rocket, NASA’s Orion spacecraft, Gateway, and human landing system are part of NASA’s backbone for deep space exploration. Under the Artemis program, NASA is working to land the first woman and the next man on the Moon to pave the way for sustainable exploration at the Moon and future missions to Mars. (NASA)

This illustration depicts the configuration of the Spacelab-2 in the cargo bay of the orbiter. Spacelab was a versatile laboratory carried in the Space Shuttle's cargo bay for scientific research flights. Each Spacelab mission had a unique design appropriate to the mission's goals. A number of Spacelab configurations could be assembled from pressurized habitation modules and exposed platforms called pallets. Spacelab-2 was the first pallet-only mission. One of the goals of the mission was to verify that the pallets' configuration was satisfactory for observations and research. Except for two biological experiments and an experiment that used ground-based instruments, the Spacelab-2 scientific instruments needed direct exposure to space. On the first pallet, three solar instruments and one atmospheric instrument were mounted on the Instrument Pointing System, which was being tested on its first flight. The second Spacelab pallet held a large double x-ray telescope and three plasma physics detectors. The last pallet supported an infrared telescope, a superfluid helium technology experiment, and a small plasma diagnostics satellite. The Spacelab-2 mission was designed to capitalize on the Shuttle-Spacelab capabilities, to launch and retrieve satellites, and to point several instruments independently with accuracy and stability. Spacelab-2 (STS-51F, 19th Shuttle mission) was launched aboard Space Shuttle Orbiter Challenger on July 29, 1985. The Marshall Space Flight Center had overall management responsibilities of the Spacelab missions.
