Mir Current Status

Along with 1000 pounds of water and two tons of new equipment and supplies, the Mir 23 crew gained a new member, U.S. Astronaut C. Michael Foale , replaced Jerry Linenger, Jerry retured to Earth with the Space Shuttle Atlantis. One of the highlights of Jerry's stay aboard Mir is his "Letters to My Son."

Jerry's stay on Mir (132 days) was the second longest space flight for a U.S. astronaut. ( Shannon Lucid currently holds the U.S. endurance record (188 days) in space.

Mike Foale is scheduled to stay four months on the Mir Space Station. He is to be relieved by U.S. Astronaut Wendy Lawrence in September 1997 when she arrives at Mir with the Space Shuttle Atlantis on the STS-86 mission.

The next Progress resupply vehicle is scheduled to be launched on June 22 and dock on June 24.

Space Shuttle Current Status

STS-84 ; SPACEHAB , MIR DOCKING, CREW EXCHANGE

The Space Shuttle Atlantis and the Russian Space Station Mir were docked for 5 days of joint operations from May 16 to May 21.

The crews of Atlantis and MIR moved more than two tones of food, water, clothing and other supplies and hardware from the Space Shuttle to Mir and moved another two tones of Russian hardware and science items from Mir to the Space Shuttle.

U.S. Astronaut C. Michael Foale became a member of the Mir crew, replacing Jerry Linenger .

Jerry's stay in space (132 days) was the second longest for U.S. astronauts. ( Shannon Lucid ) currently holds the U.S. endurance record in space.

On Flight Day 7 of the STS-84 mission, Space Shuttle Pilot Eileen Collins undocked Atlantis from Mir and slowly brought her ship away from the Russian space station. Collins held position at 90 feet and at 300 feet from Mir to conduct proximity sensor equipment experiments. Proximity data collection continued until the Atlantis reached a distance of 3300 feet below Mir when orbital forces begin to move the shuttle ahead of the station.

Atlantis and crew landed at the Kennedy Space Center May 24, 1997, at 9:28 a.m. (EDT)


STS-94

STS-94 , scheduled to be launched on July 1, 1997, is the reflight of the STS-83 mission. STS-83, with its primary payload, the Microgravity Science Laboratory-1 (MSL-1, featuring 19 materials science investigations) was launched on April 4th, 1997 for a 16 day mission, but was required to return after only 4 days due to the failure of one of Columbia's three electricity-generating fuel cells.

1st Crew Press Conference


On May 21, 1997, the first crew of the International Space Station held a press conference at the Johnson Space Center. Commander Bill Shepherd, Soyuz Commander Yuri Gidzenko and Flight Engineer Sergei Krikalev. Scheduled to launch aboard a Soyuz spacecraft in January 1999, the three will spend 5 months onboard before they change command with a crew arriving on a space shuttle and will return with that shuttle. May 21, 1997 JSC Press Conference

The Space Station Control Board approved a new baseline schedule that targets the first station launch for June 1998. This is an eight-month delay from the previous schedule and is the "direct result of funding delays in the construction of the service module, the primary Russian contribution to the early assembly of the station and a component that will supply the early living quarters, life support systems and propulsion."

The Russian funding has resumed and work is now rapidly progressing. Liftoff - Space Station

Planetary Probe Updates
SPACECRAFT
STATUS
Galileo

Launch: 18 Oct 1989
Jupiter Arrival: 7 Dec 1995

Galileo Jupiter Orbit Tour
Jun 96 - Nov 97

Where's Galileo Right Now?


REMAINING ENCOUNTERS:

"C9" 25 June 1997
"C10" 17 Sep 1997
"E11" 6 Nov 1997

On Sunday, May 25, the Galileo spacecraft will slip behind Jupiter and pass through an 18 hour occultation of the Earth by Jupiter. The radio science team will measure the changes in the spacecraft's signal as it slowly passes through the outermost atmosphere of Jupiter until it fades out, being eclipsed by the planet. These measurements will allow the determination of temperature and windspeeds in the areas of Jupiter's atmosphere that the signal passes through.

The Galileo spacecraft is continuing to playback data gathered during its previous "Ganymede 8" encounter. Ganymede 8 was the eighth orbit of the eleven (11) orbit tour of Jupiter.

Data to be played back this week include observations designed to catch volcanic plumes in action on Io. Observations were made of Io's limb (edge) against a dark sky background in the hope of seeing the faint, thin plumes. 10 different Io plume regions were observed during the previous encounter.

(Ref: This Week on Galileo May 19-25, 1997 )

Mars Pathfinder

Launch: 4 December 1996
Landing: 4 July 1997

CURRENT POSITION

The Mars Pathfinder team has been busy preparing for the upcoming landing of their spacecraft.

The team has completed the second of three Entry, Descent, and Landing (EDL) Operations Readiness Tests.

"The Mars Pathfinder spacecraft remains in good health"

(Ref: Mars Pathfinder Mission Status 16 May 1997

Mars Pathfinder is scheduled to land in Ares Vallis, (19.5N,35.8W) Mars, on July 4, 1997.

Mars Global Surveyor

Launch: 7 Nov 1996
Arrival: 12 Sep 1997

UPCOMING MISSION EVENTS

On May 8th the Mars Global Surveyor spacecraft automatically put itself in a "safe-mode" due to an unexpected event occuring in one of the spacecraft's subsystems. Engineers on the flght team determined that the safe-mode was caused by a software task that had timed out and failed to report back to the Surveyor's central computer. The flight team reproduced the safe-mode entry conditions in the spacecraft simulator and have determined the modifications required to be made to the software to avoid a recurrence.

On Monday, May 19, commands to begin recovering the spacecraft to its normal operating state will be transmitted. Normal operations are expected to be restored by May 21.

"Although the spacecraft is currently operating in safe mode, all systems are functioning properly, and not spacecraft hardware problems exist that pose a threat to the mission." (Ref: Flight Status Report - Friday 16 May 1997 )

Mars Orbit Insertion (MOI) burn to occur 12 Sep 1997. Orbit Insertion phase will last 5 months using aerobraking and propulsive maneuvers. Mapping phase from 15 March 98 to 31 Jan 2000.

(Ref: NEAR Weekly Report - 5/16/97 )

On June 27, 1997 the NEAR spacecraft will pass within 1,200 kilometers (750 miles) of asteroid 253 Mathilde.

Approximately 61 kilometers (38 miles) in diameter, Mathilde will be the largest asteroid to be encountered by a spacecraft. The NEAR spacecraft encounter with 253 Mathilde will produce the first close-up images of a C-class asteroid.

Lunar Prospector

Launch: 24 Sep 1997

To be launched on September 24, 1997, the Lunar Prospector will conduct a low polar orbit investigation of the moon. Data from the spacecraft will allow the compositional mapping of the moon, including possible water ice deposits trapped in permanently shadowed areas near the lunar poles. Other instruments will measure the crustal magnetic field, gravity fields and radon outgassing.
Cassini/Huygens

Launch: Oct-Nov 97
Arrival: 1 Jul 2004

Spacecraft Testing for the October-November 1997 launch of the Cassini/Huygens probe is currently being conducted.
