Top 10 astronautics facts Selected as the most interesting among astronautics related questions in Astronautics quiz Does the candle burn more or less violently in zero gravity?Less violently. In zero gravity no convection occurs, that normally shapes the flame, disperses CO2 and brings fresh air to the wick. Without convection, CO2 from combustion does not disperse as readily and tends to smother the flameCreated by: Kasiaphysics facts » Who built the first rocket powerful enough to enter outer space?Germans. V2, built by Wernher von Braun, was the first ballistic missile that could reach outer space. It was specifically targeted at London. Nazis also planned submarine-towed launch platforms, that would have allowed a U-boat to launch V-2 missiles against the United States.Created by: Kasiarockets facts » Which space rocket was the most powerful ever?Saturn V sent astronauts to the Moon. Fully fueled it had a total mass of 6.5 million pounds (3,000 metric tons) and a payload capacity of 260,000 pounds (120,000 kg). Its engines were heard from 50 miles away.Created by: KasiaNASA facts » How does the candle flame look like in zero gravity?It is spherical. The shape of flame is created by convection under normal gravity conditions. Without gravity, no convection occurs and the flame becomes spherical.Created by: Kasiachemistry facts » How long did it take Apollo 11 flight to reach the Moon? 3 days. It took 1 minute of flight to reach Mach 1 and 12 minutes to enter Earth's orbit. After one and a half orbits, the third-stage engine pushed the spacecraft onto its three-day long travel to the Moon.Created by: Hitter smasherspace facts » How long did Neil Armstrong’s first moon walk last?2½ hours. Each of the subsequent five Apollo program landings were allotted gradually longer periods for EVA activities – the crew of Apollo 17, by comparison, spent over 22 hours exploring the lunar surface.Created by: globalquiz.orgMoon facts » This plaque, carried by Pioneer 10 and Pioneer 11 space probes, describes the location of the Sun. What are the points at the ends of the lines?Pulsars. Each of the line includes binary encoding of pulsar frequency, so these can be easily recognized. The hydrogen spin-flip transition frequency is used as the unit of time (Hydrogen particle at the top of the image).Created by: Sophie Lethermanastronomy facts » What was the name of spacecraft in which the first three astronauts were killed?Apollo I. Apollo 1 was scheduled to be the first manned mission to the Moon. On January 27, 1967, a cabin fire during a launch pad test at Cape Canaveral killed all three crew members (pictured). The ignition source was never identified, but many lethal design and construction flaws were identified after the accident. The manned phase of the project was delayed for 20 months while those problems were corrected.Created by: globalquiz.orgNASA facts » Where is the Baikonur Cosmodrome?In Kazakhstan. Baikonur Cosmodrome is located in the center of Kazakhstan on the right bank of the Syr Darya river. Both the space launch facility and the neighboring city of Baikonur are rented and administered by the Russian Federation.Created by: globalquiz.orgKazakhstan facts » On which continent is the main spaceport of the European Space Agency located?In South America. The Guiana Space Centre is a French and European spaceport near Kourou in French Guiana since 1968. The location was chosen as it fulfills the two major geographical requirements of such a site: it is quite close to the equator, so that the spinning earth can impart some extra velocity to the rockets for free when launched eastward, and it has open sea to the east, so that lower stages of rockets and debris from launch failures cannot fall on human habitations.Created by: globalquiz.orggeography of France facts » Play astronautics quiz and see all the questions.
