SpaceX Countdown is Progressing Smoothly

SpaceX Dragon
ISS034-E-060222 (3 March 2013) — This is one of a series of photos taken by the Expedition 34 crew members aboard the International Space Station during the March 3 approach, capture and docking of the SpaceX Dragon. Thus the capsule begins its scheduled three-week-long stay at the orbiting space station.

NASA television coverage for today’s scheduled launch of the sixth SpaceX commercial resupply services mission to the International Space Station has begun and can be seen at https://www.nasa.gov/nasatv.

Countdown is progressing smoothly toward a scheduled lift off at 4:10:41 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. The weather forecast remains at 60% “go” with concerns for anvil and cumulous clouds.

The Falcon 9 rocket will launch a Dragon spacecraft carrying about two tons of supplies and materials to support about 40 of more than 250 science and research investigations that will occur during the station’s Expeditions 43 and 44.

Dragon Launch Occuring No Earlier Than Jan. 6

The SpaceX Dragon
The SpaceX Dragon commercial cargo craft approaches the International Space Station on Sept. 23, 2014 for grapple and berthing.

NASA and SpaceX announced today the launch of SpaceX’s fifth commercial resupply services mission to the International Space Station now will occur no earlier than Tuesday, Jan. 6. This will provide SpaceX engineers time to investigate further some of the issues that arose from the static fire test of the Falcon 9 rocket on Dec. 16 and will avoid beta angle constraints for berthing the Dragon cargo ship to the station that exist through the end of the year.

Beta angles are the angles between the space station orbital plane and the sun, resulting in the station being in almost constant sunlight for a 10 day period. During this time, there are thermal and operational constraints that prohibit Dragon from berthing to the station. This high beta period runs from Dec. 28 through Jan. 7.

The new launch date also will allow the teams to enjoy the holidays.

Space station managers will meet on Monday, Jan. 5, for a thorough readiness review in advance of the Jan. 6 launch attempt. The launch postponement has no impact on the station’s crew, its complement of food, fuel and supplies and will not impact the science being delivered to the crew once Dragon arrives at the station.

A launch on Tuesday, Jan. 6, is scheduled at approximately 6:18 a.m. EST. NASA TV coverage will begin at 5 a.m.

A backup launch attempt is available on Wednesday, Jan. 7.

A launch on Jan. 6 will result in a rendezvous and grapple of Dragon on Thursday, Jan. 8, at approximately 6 a.m. NASA TV coverage will begin at 4:30 a.m. Installation coverage will begin at 9 a.m.

Prelaunch briefings at NASA’s Kennedy Space Center will be rescheduled for Monday, Jan. 5 with the times to be determined.

Expedition 42 Stays Busy as NASA Preps for Orion Launch

NASA Astronaut Terry Virts
iss042e016770 (Nov. 27, 2014) — Flight Engineer and NASA astronaut Terry Virts works out on an exercise bicycle in the Destiny laboratory.

The six-member Expedition 42 crew aboard its orbital home and laboratory is conducting international science and advanced maintenance. Back on the ground, NASA is preparing for the launch of its new Orion spacecraft from Kennedy Space Center (KSC) on its first test flight, the Exploration Flight Test-1 (EFT-1) mission. The International Space Station is providing valuable experience and research that will help further future exploration missions on Orion.

The week-long servicing of the Carbon Dioxide Removal Assembly continued Wednesday as astronauts Barry Wilmore and Terry Virts replaced filters and checked for leaks. The device removes humidity and carbon dioxide from the station’s environment.

Italian astronaut Samantha Cristoforetti was in Europe’s Columbus lab module cleaning the BioLab. The facility allows the observation of micro-organisms, plants and invertebrates and their adaptation to microgravity. The cosmonauts in the station’s Russian segment gathered in Japan’s Kibo lab module to record a televised event in between their regularly scheduled duties.

At KSC, Orion will launch atop a Delta IV Heavy rocket Thursday at 7:05 a.m. EST for a two-orbit test mission taking it 3,600 miles above Earth’s surface. EFT-1 will last less than 4-1/2 hours and will end when Orion splashes down in the Pacific Ocean for recovery by NASA personnel.
