Space & Planetary Science: October 2013 Archives

Sun Emits Third Solar Flare in 2 Days

"Oct. 25, 2013 Another solar flare erupted from the same area of the sun on Oct. 25, 2013,which peaked at 11:03 a.m. EDT. This flare is classified as an X2.1 class. The sun emitted a significant solar flare, peaking at 4:01 a.m. EDT on Oct. 25, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours."

Stunning View From High Above Saturn

"This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected for shifts in the spacecraft perspective and still has some camera artifacts."

Keith's note: The following is being sent out by the Kepler SciCon organizers:

"We have just learned that the efforts of NASA's Ames Research Center to ensure that our Chinese astronomer colleagues will be able to attend the Second Kepler Science Conference have been halted by the fact these approvals must be entered into a computer system at NASA HQ in Washington DC. Because of the ongoing federal government shutdown, there is no one at NASA HQ who can complete the approval process. Of course, if the federal shutdown continues much longer, the conference will not be able to begin as scheduled on November 3, 2013. We fear that the meeting may have to be cancelled as a result, or delayed. The ability of scientists to attend an open scientific meeting about the spectacular results produced by NASA's Kepler Space Telescope is another likely fatality of the failure of the U.S. Congress to enact a federal budget for FY2014. Alan Boss, SOC Co-Chair, KSC II"

Keith's note: As I understand the situation all of the final arrangements for this meeting - including the processing of all foreign visitors (not just Chinese) - can only happen if the government is open. If the government does not open in time then there's a chance that the meeting simply will not happen. And of course, Frank Wolf voted for the shutdown ...

Juno Earth Flyby Today

Juno Prepares For Earth Flyby on Wednesday

"The flyby will function as a gravity assist for Juno, with Earth's gravity accelerating the solar-powered spacecraft's velocity by 16,330 miles per hour. NASA launched Juno to an area just past Mars, then two main engine burns executed a year ago maneuvered it back around toward Earth. The purpose of using a gravity assist to get Juno on its way to Jupiter is one of cost."

LADEE Makes LOI-2 Burn

Keith's note: According to someone at NASA: "LADEE just completed a successful firing of its main engine in the second lunar orbit insertion (LOI-2) burn! We are now in a 4 hour elliptic orbit, with the perilune at our commissioning altitude. This follows the LOI-1 burn on Oct 6 that first got us into lunar orbit. The accuracy of the LOI-1 burn was such that we did not need to do the LAM-1 (apolune) maneuver. The final of the three LOI burns is scheduled for October 12. This will settle us into the commissioning orbit."

LADEE Is Orbiting The Moon

Keith's note: According to someone at NASA: "Early this morning (October 6), we fired LADEE's main engine in a braking maneuver known as the Lunar Orbit Insertion (LOI) burn. This slowed the spacecraft's velocity enough for it to be captured by the Moon's gravity. This critical burn went flawlessly and LADEE is now in lunar orbit! Two more main engine burns, on October 9 and 12 will adjust LADEE's trajectory, settling it into its commissioning orbit."

US scientists boycott Nasa conference over China ban, Guardian

"Nasa officials rejected applications from Chinese nationals who hoped to attend the meeting at the agency's Ames research centre in California next month citing a law, passed in March, which prohibits anyone from China setting foot in a Nasa building. The law is part of a broad and aggressive move initiated by congressman Frank Wolf, chair of the House appropriations committee, which has jurisdiction over Nasa. It aims to restrict the foreign nationals' access to Nasa facilities, ostensibly to counter espionage."

Keith's note: Some of the scientists who are quoted in this article with complaints about NASA have apparently been living under a rock for the past several years. Newsflash: It is utterly illegal for NASA to allow Chinese participation - in any way. Complaining about NASA's decision is simply ill-informed. Where were all these people when this law was being formulated - or when hearings were held on it? Dumping on NASA or boycotting this meeting is pointless - only Kepler will suffer. If a change in the law is what is needed then these people need to talk to Congress about that - starting with Rep Wolf.

Check H.R. 1473 (112th): Department of Defense and Full-Year Continuing Appropriations Act, 2011, Sec. 1340. (a) to see the sort of prohibitive language has been in place for several years. NASA's hands are tied.

Keith's note: As NRAO lays everyone off and starts to go dark, it posted this really nice promotional video for the VLA narrated by Ellie Arroway aka Jodie Foster.

If you go to NRAO you get a shutdown notice: "Effective 7 p.m. EDT, Friday, 4 October 2013, the National Radio Astronomy Observatory (NRAO) temporarily suspended all operations because of the US Federal government shutdown."

US Antarctic research season is in jeopardy, Nature

"The National Science Foundation (NSF) is likely to cancel the US Antarctic programme's upcoming field season if the US government shutdown persists through mid-October -- jeopardizing hundreds of scientists' work in glaciology, ecology and astrophysics. The agency has kept its three Antarctic research stations open during the initial days of the shutdown, which began on 1 October, under rules designed to protect human lives and US government property. But Lockheed Martin, the contractor that runs the NSF's Antarctic operations, has told researchers that it will run out of money by mid-October."

Government Shutdown Mars Arecibo Anniversary, Space News

"Operations of the Arecibo Observatory in Puerto Rico are continuing for the moment despite the shutdown, observatory director Robert Kerr said at an Oct. 2 press conference here. He said the National Science Foundation, Arecibo's principal funder, authorized the observatory to spend what remaining funds it has on hand, although because the shutdown occurred at the beginning of the new fiscal year, there are few such funds available."

NASA's MAVEN's Mission Spared from Shutdown, Planetary Society

"In an increasingly rare display of sanity from Washington, NASA's Mars Atmosphere and Volatile Evolution Mission (MAVEN) was declared "excepted" from the current government shutdown so preparations for its November launch could continue. Bruce Jakosky, the Principle Investigator for the MAVEN mission, shared the news."
