On Feb. 28, 1990, space shuttle Atlantis took off from NASA’s Kennedy Space Center in Florida on STS-36, the sixth shuttle mission dedicated to the Department of Defense. As such, many of the details of the flight remain classified. The mission marked the 34th flight of the space shuttle, the sixth for Atlantis, and the fourth night launch of the program. The crew of Commander John Creighton, Pilot John Casper, Mission Specialists Mike Mullane, David Hilmers, and Pierre Thuot flew Atlantis to the highest inclination orbit of any human spaceflight to date. During the four-day mission, the astronauts deployed a classified satellite, ending with a landing at Edwards Air Force Base in California.

NASA In February 1989, NASA assigned astronauts Creighton, Casper, Mullane, Hilmers, and Thuot to the STS-36 mission. The mission marked the second spaceflight for Creighton, selected as an astronaut in 1978. He previously served as the pilot on STS-51G. Mullane, also from the class of 1978, previously flew on STS-41D and STS-27, while Hilmers, from the class of 1980, previously flew on STS-51J and STS-26. For Casper and Thuot, selected as astronauts in the classes of 1984 and 1985, respectively, STS-36 marked their first trip into space.

The orbiter spent a then-record 75 days in the processing facility and assembly building, rolling out to Launch Pad 39A on Jan. 25, 1990. The astronauts arrived on Feb. 18 for the planned launch four days later. First Creighton, then Casper and Hilmers, came down with colds, delaying the launch to Feb. 25. Weather and hardware problems pushed the launch back to Feb. 28, giving the astronauts time to return to Houston for some simulator training. On launch day, winds and rain delayed the liftoff for more than two hours before launch controllers gave Atlantis the go to launch.
Liftoff of space shuttle Atlantis on STS-36. NASA With mere seconds remaining in the launch window, Atlantis lifted off at 2:50 a.m. EST Feb. 28, to begin the STS-36 mission. Atlantis flew an unusual dog leg maneuver during ascent to achieve the mission’s 62-degree inclination. Once Atlantis reached orbit, the classified nature prevented any more detailed public coverage of the mission. The astronauts likely deployed the classified satellite on the mission’s second day. During the remainder of their mission, the astronauts conducted several experiments and photographed preselected areas and targets of opportunity on planet Earth. Their high-inclination orbit enabled them to photograph areas not usually seen by shuttle crews.

On March 4, Creighton and Casper brought Atlantis to a smooth landing at Edwards Air Force Base after 72 orbits of the Earth and a flight of four days, 10 hours, and 18 minutes. About an hour after touchdown, the astronaut crew exited Atlantis for the ride to crew quarters and the flight back to Houston. Later in the day, ground crews prepared Atlantis for the ferry ride back to Kennedy. Atlantis left Edwards on March 10 and three days later arrived at Kennedy, where workers began to prepare it for its next flight, STS-38 in November 1990.

Credit: NASA NASA has selected SpaceX of Starbase, Texas, to provide launch services for the Near-Earth Object (NEO) Surveyor mission, which will detect and observe asteroids and comets that could potentially pose an impact threat to Earth.
The firm fixed price launch service task order is being awarded under the indefinite delivery/indefinite quantity NASA Launch Services II contract. The total cost to NASA for the launch service is approximately $100 million, which includes the launch service and other mission related costs. The NEO Surveyor mission is targeted to launch no earlier than September 2027 on a SpaceX Falcon 9 rocket from Florida.
The NEO Surveyor mission consists of a single scientific instrument: an almost 20-inch (50-centimeter) diameter telescope that will operate in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, the latter being the most difficult type to find with existing assets. The space telescope is designed to help advance NASA’s planetary defense efforts to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit. These are collectively known as near-Earth objects, or NEOs.
The mission will carry out a five-year baseline survey to find at least two-thirds of the unknown NEOs larger than 140 meters (460 feet). These are the objects large enough to cause major regional damage in the event of an Earth impact. By using two heat-sensitive infrared imaging channels, the telescope can also make more accurate measurements of the sizes of NEOs and gain information about their composition, shapes, rotational states, and orbits.
The mission is tasked by NASA’s Planetary Science Division within the agency’s Science Mission Directorate at NASA Headquarters in Washington. Program oversight is provided by NASA’s Planetary Defense Coordination Office, which was established in 2016 to manage the agency’s ongoing efforts in planetary defense. NASA’s Planetary Missions Program Office at the agency’s Marshall Space Flight Center in Huntsville, Alabama, provides program management for NEO Surveyor. The project is being developed by NASA’s Jet Propulsion Laboratory in Southern California.
Multiple aerospace and engineering companies are contracted to build the spacecraft and its instrumentation, including BAE Systems SMS (Space & Mission Systems), Space Dynamics Laboratory, and Teledyne. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, will support operations, and the Infrared Processing and Analysis Center at the California Institute of Technology (Caltech) in Pasadena, California, is responsible for processing survey data and producing the mission’s data products. Caltech manages JPL for NASA. Mission team leadership includes the University of California, Los Angeles. NASA’s Launch Services Program at the agency’s Kennedy Space Center in Florida is responsible for managing the launch service.
