| ||||| Monday, January 21, 2002 - 12:45 pm Which shuttle astronaut is a veternarian? | |
| ||||| Tuesday, January 22, 2002 - 11:10 am That would be Richard Linnehan. | |
| ||||| Tuesday, January 22, 2002 - 07:21 pm HELLO I WAS WONDERING WHY THE SHUTTLES TURN 180 AFTER TAKE OFF ? | |
| ||||| Wednesday, January 23, 2002 - 08:38 am The Space Shuttle lifts off the pad 0.3 second after SRB ignition, rising vertically in attitude hold until the SRB nozzles clear the lightning rod tower by approximately 41 feet. The vehicle then begins a combined roll, pitch and yaw maneuver that positions the orbiter head down, wings level, aligned with the launch pad. The orbiter flies upside down during the entire ascent phase. This orientation, together with trajectory shaping, establishes an angle of attack that is favorable for aerodynamic loads during the region of high dynamic pressure, resulting in a net positive load factor, as well as providing the flight crew with use of the ground as a visual reference. By about 20 seconds after lift-off, the vehicle is at 180 degrees roll and 78 degrees pitch. PS, I can't take credit for this answer, I found it on http://www.madsci.org/ HSTGUY | |
| ||||| Thursday, January 24, 2002 - 03:22 pm how many missions has the space shuttle flown? | |
| ||||| Thursday, January 24, 2002 - 03:37 pm There have been 107 flights with 5 orbiters (currently 4 are active). Flights per orbiter and full program chronology is here: http://spaceflightnow.com/shuttle/sts109/fdf/images/stschrono.gif | |
| ||||| Friday, January 25, 2002 - 12:19 pm WHAT DOSE A HUBBLE LOOK LIKE. | |
| ||||| Friday, January 25, 2002 - 01:59 pm You can see a couple shots of hubble on this website at: hubble pics Or you can go to the main Hubble site and look through the image gallery: more hubble pics | |
| ||||| Tuesday, January 29, 2002 - 12:53 pm during the inital burn, is the shuttle still helded in place, or is it now release to lower the effects of acoustic/vibration on craft, crew and equipment. | |
| ||||| Tuesday, January 29, 2002 - 01:30 pm BTW, someone should move the HST fit check trainer alittle to the left in the Goddard/NASA cleanroom, you can't view the VEST. | |
| ||||| Tuesday, January 29, 2002 - 03:40 pm It seems there are a few complex stages involved in engine start, rocket ingintion, and release. So I can't be sure but it seems the shuttle is held for for a few seconds when the engines are started and for a fraction of second when the rockets are ignited. You be the judge: countdown | |
| ||||| Wednesday, January 30, 2002 - 07:41 am The concern I heard, was that after all engines; shuttle and solid, were lit, the craft was being held in place too long, adding extra strain due to vibration, to shuttle, crew and equip onboard. Any truth in this. | |
| ||||| Wednesday, January 30, 2002 - 05:05 pm Where can I find more information on how the Advanced Camera for Surveys system will work? | |
| ||||| Wednesday, January 30, 2002 - 05:22 pm Shuttle held too long before liftoff? I would hope the engineers would have calculated when is the best time to release the shuttle accounting for the vibrations and strain, but other than that, I don't know. Any rocket scientists out there? | |
| ||||| Wednesday, January 30, 2002 - 05:24 pm For more technical info on ACS, go to: ACS info | |
| ||||| Tuesday, February 05, 2002 - 08:22 pm where can I find illustrations of the progressional changes the Hubble has gone/will go through? I have seen all of the stages up to 3B and figure that someone has to have an idea what Hubble will look like with each change. | |
| ||||| Wednesday, February 06, 2002 - 02:58 pm Until after this upcoming mission, the appearance of Hubble hasn't changed that much. Most of the changes occur with instruments on the inside. We have replaced the solar arrays before, but SA1 and SA2 were not dramatically different. If you'd like to see the change after the SM3B mission we've recently posted a computer rendition at: SM3B objectives | |
| ||||| Wednesday, February 06, 2002 - 03:39 pm I would like to say a very special thanks to Kathy Massetti who has open my eyes to another world. This is the first time that I had taken time to look at any project mission. I was truly missing history in action. I believe that I'm hooked. Thanks again Kathy!!! | |
| ||||| Thursday, February 07, 2002 - 05:17 pm I'll try to make sure she gets your message. If you haven't seen them already, we have a few clips from an interview with Kathy: interview clips | |
| ||||| Wednesday, February 13, 2002 - 05:31 pm hello, i was just wondering (actually it is required for my college course) when did the sation circle over st.louis missouri and people could actually see it. . .if you could answer this question it would be great! Thanks and have fun up there. | |
| ||||| Monday, February 18, 2002 - 11:14 am NASA indicates that the HST will come to an end in 2010. Since we have spent so much time and money and obtained such great science from it, why? I understand it costs a lot to service the telescope, but there is a plan to build a new bigger one in the near future. Given that, then the cost to service HST would only be the cost of an additional stop up there, not near the total cost of the whole trip. We could use HST in tandem with the other telescope and achieve some characteristics that would be equivalent to a mirror as big as the separation of the two telescopes in space!! Also, HST could be used to relieve the work load of the new telescope. All astronomy does not have to be done with the latest and greatest. Telescopes on earth are not destroyed when newer, bigger telescope become available, they are just relegated to less critical jobs. | |
| ||||| Monday, February 25, 2002 - 10:47 am After reading the profiles on the astronauts for this next mission, I see that there is a lot of experienced flyers. All but one are veterans in space. Is this because of the nature of the mission? (very complex) Or are we now getting enough space flight time and it should be expected? Thanks, Don | |
| ||||| Monday, February 25, 2002 - 09:06 pm Personally I think it is a combination. The mission is very complex so it may be easier for veterans. However we also have many more astronauts and missions than we used to, so there simply are more veterans. | |
| ||||| Friday, March 01, 2002 - 11:18 am Hi, Will we get to see the burn? | |
| ||||| Sunday, March 03, 2002 - 10:47 am Bugsy, if you are refering to the burns that the shuttle does while in space, the answer is yes. The OMS engines' and the Reaction Control System's plumes appear like bright puffs. | |
| ||||| Sunday, March 03, 2002 - 11:34 am Congratulations to all the crew members who so successfully snagged the Hubble - but especially to Nancy Currie. I will highlight your efforts as part of my focus on women of note during this month (Women's History Month) for my eighth graders at Our Lady of Mercy H.S. in Rochester, NY. "Hubble on your arm" - now, here is a lady with fine taste in bracelets! Great work! | |
| ||||| Sunday, March 03, 2002 - 12:35 pm I HAVE A TELESCOPE, ANY CHANCE OF ME CATCHING A GLIMPS OF YOU GUYS OR THE HUBBLE? | |
| ||||| Sunday, March 03, 2002 - 12:42 pm Take a look at the Where is Hubble applet. Tells you when HST is next viewable from your location. | |
| ||||| Sunday, March 03, 2002 - 01:09 pm DC2KEB02, Let me add that your best bet viewing is to start with the naked eye and then go to binoculars once you have it spotted. Satellites travel relatively quickly across the sky. | |
| ||||| Monday, March 04, 2002 - 12:10 pm How big is the scope and how strong is it? | |
| ||||| Wednesday, March 06, 2002 - 02:59 pm What does this whole repair mission cost NASA? | |
| ||||| Wednesday, March 06, 2002 - 05:01 pm About the cost.... The hardware in the Cargo Bay is about 175M$, the Shuttle flight several hundred million depending on how you count the costs. A 100M$ here, 100M$ there, pretty soon you are talking some real money...... | |
