The HST was carried aboard the Space Shuttle and placed in orbit in April of 1990.
Four Shuttle missions visited it between 1993 and 2002 for service, upgrade,
and maintenance. A planned fifth mission was cancelled in the aftermath of the
Columbia disaster. However, after much public discussion, NASA administrator
Mike Griffin approved one final servicing mission. It was completed in 2009, and
there won't be any more.
The Hubble telescope is now expected to function until at least 2014, and
possibly 2020. Its scientific successor, the James Webb Space Telescope,
is scheduled to be launched in 2018.
The HST sends 120 gigabytes of science data every week. This includes photos. Such data downloads are made every day.
Those Apollo missions were unmanned hardware test flights, and often fall under different designations. Apollo 2 is actually named AS-201 and Apollo 3 is AS-202.
There were a total of 14 missions There were 3 unmanned missions (Apollo4, Apollo5, Apollo6), 3 manned missions into Earth orbit.(Apollo7, Apollo8, Apollo9) 6 missions landed on the moon. The first two flights (11 and 12) included successful Moon landings. The Apollo 13 mission was aborted before the landing attempt, but the crew returned safely to Earth. The four subsequent Apollo missions (14 through 17) included successful Moon landings. The last three of these were J-class missions that included the use of Lunar Rovers. Apollo 17 launched December 7, 1972 and was the last Apollo mission to the moon. The Apollo spacecraft and Saturn launch vehicles were later used for the Skylab program and the joint American-Soviet Apollo-Soyuz Test Project. These later programs are thus often considered to be part of the overall Apollo program. The were no missions named Apollo 1, 2 or 3. They were called SA-1 SA-2 and SA-3. They were test launches of the Saturn V rocket and the Apollo capsule.
Viewing a shuttle launch is a once in a lifetime experience for many, so one answer is whenever you get the opportunity. Many who have seen multiple launches state that night launches are their favorites. From a practical point of view, launches scheduled for times and dates where weather is less likely to cause delays are the best. Launches scheduled for summer afternoons and evenings are the most likely to be scrubbed due to the often volatile weather conditions.
Mars, often called the "Red Planet," is the fourth planet from the Sun in our solar system. It's known for its reddish appearance due to iron oxide (rust) on its surface. Here's a brief overview: **Physical Characteristics**: Mars has a thin atmosphere composed mostly of carbon dioxide. It has polar ice caps, which consist of water and frozen carbon dioxide. The planet has diverse terrain, including mountains, valleys, and vast plains. **Moons**: Mars has two small moons, Phobos and Deimos, which are irregularly shaped and likely captured asteroids. **Exploration**: Mars has been the subject of numerous space missions. Notable ones include the Viking missions in the 1970s, the Mars rovers Spirit, Opportunity, and Curiosity, and more recent missions like NASA's Perseverance rover. **Potential for Life**: Mars is a prime target for the search for past or present life beyond Earth. Evidence suggests that liquid water existed on its surface in the past, and there are regions where it may still exist underground. **Future Missions**: Several space agencies and private companies have plans for future missions to Mars, including crewed missions. These missions aim to further explore the planet, study its geology, and potentially prepare for human settlement. **Challenges**: Mars exploration poses numerous challenges, including the harsh environment, distance from Earth, and the need for advanced technology to support human life. Overall, Mars continues to captivate the imagination of scientists and space enthusiasts alike as humanity explores the possibilities of reaching and even colonizing the Red Planet.
Space Shuttles Discovery and Atlantis were most often used for HST Servicing Missions, due to their larger cargo bays.
HST Servicing Mission 4 was carried out in 2009 aboard Space Shuttle Atlantis, during shuttle mission STS-125. Atlantis and Discovery were the most often used shuttles for HST servicing missions, due in large part to their larger cargo bays compared to the other shuttles.
The Hubble was launched in April 1990. Since launch it's had 5 servicing missions, the last being in May 2009, which means the average time between servicings was slightly under four years. The longest time was between the fourth and fifth missions ... about seven years. The Hubble is projected to remain operational until 2014. It's unlikely that there will be another servicing mission, unless the final deorbiting is counted. This will probably happen sometime between the end of its useful life and 2025, by which time it will be in severe danger of experiencing an uncontrolled reentry. This would be bad, since the Hubble is quite large for a satellite and there's a good possibility that substantial chunks of it will survive reentry and impact the Earth's surface. A controlled deorbit will allow it to be brought down safely in the middle of the ocean as opposed to, say, over Los Angeles or Tokyo or London. The last servicing mission installed a docking ring to allow a future unmanned robotic spacecraft to dock with the Hubble and deorbit it.
Between 1994 and 2002, the solar panels on the Hubble were struck an estimated 725,000 times by space junk.

Mr. Hubble is a character in Charles Dickens' novel Great Expectations. He is the husband of Mrs. Joe Gargery's sister, Mrs. Hubble. Mr. Hubble is a mild-mannered man who often defers to his wife's strong personality.
Since I am unable to access records for testing, I am unable to assist you with this question. I recommend speaking with Amber's teacher or professor to see how often she is scheduled for Jam Testing.
So far, they seem to be releasing Super Moshi Missions about once a month.
