Falcon 9 launches cargo Dragon mission to ISS

WASHINGTON — SpaceX launched a cargo Dragon mission to the Worldwide Area Station as the corporate and NASA reaffirmed their dedication to security.

A Falcon 9 lifted off at 9:29 p.m. Japanese Nov. 4 from Kennedy Area Middle’s Launch Advanced 39A. The rocket deployed the Dragon spacecraft into low Earth orbit 9 and a half minutes later.

The spacecraft, flying a mission designated CRS-31 or SpX-31, is scheduled to dock with the ISS at about 10:15 a.m. Japanese Nov. 5.It would dock with the ahead port on the Concord module, which was freed up for the cargo Dragon when the Crew-9 Crew Dragon spacecraft undocked from that port and moved to the alternate zenith docking port on Concord throughout a 50-minute maneuver early Nov. 3.

The cargo Dragon is delivering 2,762 kilograms of cargo to the station. That could be a comparatively routine mixture of crew provides, science investigations and different {hardware} for the station. The 56 science investigations vary from an instrument referred to as the Coronal Diagnostic Experiment (CODEX) that shall be mounted on the station’s exterior to observe the solar’s corona to ARTEMOSS, an experiment to check how an Antarctic moss handles the radiation and microgravity circumstances of area to see if it might be appropriate for future bioregenerative life help techniques.

The mission, whereas comparatively routine, does function some improvements. The separation of the Dragon from the Falcon 9 higher stage happened 145 seconds sooner than on previous missions. Jared Metter, director of flight reliability at SpaceX, stated at a Nov. 4 prelaunch briefing that the corporate beforehand had an extended hole between shutdown of the higher stage’s engine and Dragon separation to make sure good perspective management and an absence of slosh within the stage’s propellants.

“As a result of now we have sufficient knowledge now to take a look at many, many missions, we will analyze and present that, by way of flight, we didn’t want that lengthy interval,” he stated.

One other change is that Dragon will, for the primary time, carry out an ISS reboost maneuver whereas docked to the station. Throughout that maneuver, scheduled for Nov. 8, Dragon will fireplace its Draco thrusters for 12 and a half minutes. NASA and SpaceX officers stated on the briefing they didn’t know the projected change in velocity and orbit of the station from that maneuver.

“This is a vital flight check goal for this mission as we proceed to extend the capabilities of all of the automobiles on ISS,” stated Invoice Spetch, ISS operations and integration supervisor at NASA.

Mettler added that the information collected through the reboost check will assist SpaceX because it develops the U.S. Deorbit Automobile (USDV), a spinoff of Dragon that it’s constructing for NASA to deal with the ultimate phases of the deorbiting the ISS on the finish of its life round 2030. NASA awarded SpaceX a contract price as much as $843 million in June to develop the USDV.

Questions of safety

NASA and SpaceX addressed security considerations about Dragon and Falcon operations raised by NASA’s Aerospace Security Advisory Panel (ASAP) at its Oct. 31 public assembly. Throughout that assembly, the panel cited current anomalies similar to higher stage malfunctions on two Falcon 9 launches.

“Each NASA and SpaceX want to take care of concentrate on secure Crew Dragon operations and never take any ‘regular’ operations with no consideration, stated former astronaut Kent Rominger, a member of the panel, on the assembly.

Spetch stated that the company will not be altering evaluations of Dragon launches in response to these anomalies or the panel’s feedback. “We conduct all of our regular evaluations. We work very intently with SpaceX on every little thing that we do relative to those Dragon launches,” he stated. “I wouldn’t say we’re doing something completely different.”

“One of many main advantages of getting so many alternatives to launch is that each launch is a chance to be taught,” Mettler stated. “We’re going to observe our commonplace course of to make sure now we have a superb mission right here.”

He added that there was no proof of what he referred to as “crossover,” or widespread causes, among the many current anomalies cited by ASAP in addition to some other observations famous on Falcon launches. “We recognized no crossover or widespread theme or systemic challenge widespread to any of those anomalies,” he stated. “We see no crossover between these occurrences.”
