1956 February 20 - . LV Family: Navaho. Launch Vehicle: Navaho.
  • North American proposes Navaho acceleration - . Nation: USA. Program: Navaho. Facing being surpassed by the fast development of the Atlas ICBM, North American proposes Project Broomstick. This would accelerate Navaho G-26 inertial-navigation-equipped dive-in flights to October 1956. This would make the vehicle expendable, removing all the likely problems in developing a recoverable vehicle that was in any case not applicable to production. Deletion of the landing gear and parachutes would also allow greater range to be demonstrated. Altogether it was believed the change would allow G-38 full-scale vehicle flights to start in June 1958 and deployment of the operational Navaho in 1960.

Soyuz TM-29 docked with Mir on February 22 at 05:36 GMT. Since two crew seats had been sold (to Slovakia and France), Afansyev was the only Russian cosmonaut aboard. This meant that Russian engineer Avdeyev already aboard Mir would have to accept a double-length assignment. After the February 27 departure of EO-26 crew commander Padalka and Slovak cosmonaut Bella aboard Soyuz TM-28, the new EO-27 Mir crew consisted of Afanasyev as Commander, Avdeyev as Engineer and French cosmonaut Haignere. Follwoing an extended mission and three space walks, the last operational crew aboard Mir prepared to return. The station was powered down and prepared for free drift mode.

Endeavour's astronauts are looking forward to using one more small bonus in mapping operations time. They were given an additional 10 minutes, bringing the total to nine days, 18 hours and 10 minutes. The additional minutes have been added to allow one more mapping pass across Australia, rather than turning off the radar just as the spacecraft approaches the nation's coastline.

  • Odin - . Mass: 250 kg (550 lb). Nation: Sweden. Agency: ZAO. Manufacturer: SSC. Class: Astronomy. Type: Infrared astronomy satellite. Spacecraft: Odin. USAF Sat Cat: 26702 . COSPAR: 2001-007A. Apogee: 580 km (360 mi). Perigee: 573 km (356 mi). Inclination: 97.7000 deg. Period: 96.20 min. Sweden's Odin scientific satellite carried a submillimeter wave astronomy instrument and a radiometer for atmospheric studies. The 1.1-meter reflector fed 500 GHz and 119 GHz radiometers and was used to study galactic molecular clouds, complementing NASA's SWAS satellite. The Odin satellite was designed and built by the Swedish Space Corporation (Svenska Rymdbolaget or Rymdaktiebolaget). SSC does most of its satellite design and construction in-house, although Saab made the antenna and carried out satellite final assembly. SSC was a goverment-owned company and a contractor for the Rymdstyrelsen (Swedish National Space Board).

The spacewalk was made from the Station's Quest airlock. Depressurization was at around 1134 UTC and repressurization was at 1725 UTC. The spacewalk involved some preparatory work with cables and thermal covers in advance of the EVA's planned for STS-110 and the installation of the S0 truss. It was also intended to check out proper functioning of the Quest airlock, which had some minor problems on its first use in July 2001.
