Цитата]Навеяно соседним топиком, о том как ракету носят на руках. В Америке, оказывается, ракеты тоже толкают руками
ЦитатаThe Lunar Reconnaissance Orbiter spacecraft has three cameras, a wide angle camera (WAC) with 100 m resolution through 7 color filters, and two narrow angle cameras (NAC) with the phenomenal resolution of half a meter. The WAC will image the entire Moon in swaths 60 km wide, but there are constraints that keep the NACs from imaging everywhere. That is why NASA must select what limited number of 5 km wide by 25 km long rectangles to target the NACs. The LRO camera team includes members who get to select these NAC targets; the blue squares represent the targets selected so far (and the black ones are data gaps in the Clementine mosaic). The majority of targets seem to be in the mare and, although you can't tell from this single hemisphere map, on the nearside. Targets include both polar regions from 80° to 90°, sites where spacecraft previously landed/crashed, lava tubes (interesting for potential human habitation), domes, spectral anomalies (like the Gruithuisen Domes), and thousands of other features of interest to the team. But they also will image some targets proposed by the public, and that means you and me! By two months before launch (now semi-scheduled for May 20) the LRO/LROC Target Selection Interface will be online and we all can add targets for possible addition to the official list. This is a chance to see favorite areas in extremely high resolution - Danny Caes can look at some of the small bright craters that fascinate him, but only 5 targets a day can be submitted. Arizona State University, which runs LROC will host an open meeting on June 9-11 to discuss NAC targeting, and since this should be a month after launch perhaps there will be some new sample images to admire.

ЦитатаWednesday, April 01, 2009NASA Moon Mission Slips to June The launch from Cape Canaveral of an unmanned NASA probe that will map lunar landing sites has been moved from May to early June, the agency has confirmed. The date change from May 20 to no earlier than June 2 allows the mission more flexibility following this Friday's scheduled launch of a military communications satellite on a United Launch Alliance Atlas V rocket.NASA's Lunar Reconnaissance Orbiter mission, also launching on an Atlas V, would have no days to spare even if the Wideband Global SATCOM-2 satellite, or WGS-2, launches as planned on Friday. The scrub of a March 17 WGS-2 launch attempt because of an oxidizer leak in the rocket's Centaur upper stage made the May timeline too tight. "With the WGS launch moving out to Friday from its original launch date, it left us with zero days of contingency, and we didn't want to go into that flow with no contingency time," said George Diller, a spokesman at Kennedy Space Center. Diller said the specific launch date in June would be refined based on the mission's science goals. Possible days early in the month include the 2nd, 3rd, 4th and 6th. More opportunities arise in the third week of June. The lunar orbiter will spend a year mapping the moon for potential landing sites for astronauts, who are scheduled to return around 2020. Read a fact sheet here. A secondary payload is the Lunar CRater Observation and Sensing Satellite. The spacecraft and the Atlas V Centaur upper stage will crash in to the Earth and record data from the plume created by the impact. The goal is to confirm the presence or absence of water ice in a permanently shadowed crater near a lunar pole, NASA says.

ЦитатаThis first picture is of the Atlas V "booster", the first stage of the launch vehicle that fires on liftoff....Notice that the rocket nozzles at the bottom of the booster have Cyrillic script on them. They're RL-10 engines, made in Russia.
ЦитатаA couple of readers brought an error to my attention regarding the type of engines used on the Atlas V. The engines are RD-180's, not RL-10's as I had originally posted. Thank you for pointing out the error! I've corrected the original post.
