Weekly Links

It has been a while since I have posted one of my weekly space news links posts. Part of the reason has been a whirlwind move that we (my girlfriend and I) made from our apartment into a new house. We currently don’t have internet, which hampers my blogging a bit. But also, I have been busy at work, including having the privilege of working rather closely on the current SpaceX mission to ISS, which has been exciting. I even attended a joint planning meeting for the mission today to talk about unberth and departure of the Dragon capsule on March 25th, which I will get to support from the Mission Control Center.

Down to Earth

It’s official. As of late last month, the US House of Representatives finally passed a bill to rename the Dryden Flight Research Center in California the Neil A. Armstrong Flight Research Center. The proposal still needs to be approved by the Senate.

An international research team working in Antarctica has found an 18 kg meteorite on the ice surface of that barren continent. This is the largest meteorite find in Antarctica since 1988.

Millionaire and former space tourist, Dennis Tito, announced last month that he intends to create a new space “adventure” (not venture) known as Inspiration Mars. The intent of the project is to send humans (ostensibly a single married couple) on a circum-Martian flight that would take about 500 days. The mission would not involve a landing on the planet, due to cost and complexity, but would seek to inspire a generation and possibly lead to greater adventures (and ventures) in the future. Color me skeptical, but I hope they can do it! Fundraising will be a challenge.

Here are some helpful ideas of how Inspiration Mars might be able to generate revenue to make their mission a success.

SpaceX did another hover test of their huge Grasshopper vertical landing test rocket. Cool stuff.

In Orbit

On March 1, SpaceX successfully launched another Dragon cargo craft to ISS on the first attempt.

SpaceX had some issues with their propellant system that delayed their spacecraft’s arrival at ISS by a day. Dragon arrived with no problems on Sunday, March 3, after many meetings to discuss the issues and agree to a replan. I was working in the Houston Mission control Center that weekend and was impressed to see the machine of mission operations chugging away to produce such a quick turnaround of the timeline!

I enjoyed watching the ISS crew open the Dragon hatch and begin unloading on Sunday evening, which I already wrote about in a previous post.

Around the Solar System

On Mars, the Curiosity rover is having some unknown computer memory issues. On February 28th, ground controllers intentionally commanded the rover to use the backup computer, which put the rover into safe mode (coincidentally, on the same day that SpaceX’s Dragon capsule was having issues). The rover is currently functioning while teams back on Earth prepare to send software “patches” to the rover later this week.

NASA’s Van Allen Probe mission has discovered a third distinct radiation belt around Earth.

This week, the comet panSTARRS is making an appearance in the Northern hemisphere’s skies. This is one of the two comets (the other being comet Lemmon) that were supposed to make a splash this year. PanSTARRS has not turned out to be dimmer than hoped, but still worth looking for. The comet just passed the sun and is coming around the other side, which is why it is fading out of peak brightness while also creeping higher above the horizon after sunset. I was able to find panSTARRS with my binoculars this evening and she is definitely pretty, if small.

Speaking of comets, a newly discovered comet, named Siding Spring, is predicted to have a very close approach of Mars (not us, phew!) in late 2014. The uncertainty in the orbit leaves the possibility open that the comet make actually impact Mars. This would be a bad day for Mars and our spacecraft stationed there. Phil Plait explores the possibility of destruction, while Emily Lakdawalla considers the more benign possibility of a nice meteor shower.
