Why can astronauts not use parachutes to help slow down their spacecraft as it approaches the moon how do they slow down their spacecraft?
A parachute would not work in the vacuum of space as there is no air for it to catch and create drag. Instead, spacecraft approaching the moon slow down through a combination of a retrograde rocket burn and gravity assist maneuvers to enter lunar orbit. Mission planners carefully calculate the spacecraft's trajectory and use precise engine firings to control its speed and trajectory.

Why can astronauts not use parachutes to heip slowdown their spacecraftsas it approaches the moon how do they slowdown their spacecraft?
Astronauts cannot use parachutes to slow down their spacecraft when approaching the Moon because there is no atmosphere on the Moon to deploy parachutes effectively. Instead, spacecraft use propulsion systems like engines or thrusters to slow down as they approach the Moon. By firing these engines in the opposite direction they are traveling, they can reduce their speed and enter lunar orbit safely.
Why can astronauts not use parachutes to help slow down their spacecraft?
Astronauts cannot use parachutes to slow down their spacecraft because there is no atmosphere or air resistance in space to deploy and manipulate the parachute. Parachutes rely on air to create drag and slow down the descent, which is not present in the vacuum of space. Spacecraft use thrusters or heat shields to control re-entry and manage their speed during re-entry into Earth's atmosphere.
How did the astornauts from Apollo 11 get back to earth?
The astronauts from Apollo 11 returned to Earth by using the Command Module, which separated from the Lunar Module after leaving the moon's orbit. The Command Module re-entered Earth's atmosphere, and parachutes slowed it down for a safe landing in the ocean. The astronauts were then picked up by a recovery team.
Can you use parachutes in space?
No, parachutes require air to create drag and slow down descent. In outer space, there is no air to provide resistance, so parachutes would not be effective. Other methods, like retro rockets or aerobraking, are used for spacecraft to slow down.
How do astronauts slow their spacecraft down when approaching the moon?
Astronauts use small bursts from little jets pointed in the direction of travel to slow down the ship when they approach the moon.

How astronauts slow their spacecraft down?
Using Reaction Control Thrusters or Cold Gas Jets (small thrusters). The astronauts fire them in the opposite direction that the spacecraft is traveling and this thrust slows down the craft.

Why should astronauts not use parachutes to land on the moon?
Astronauts should not use parachutes to land on the Moon because the Moon has no atmosphere, meaning there is no air resistance to slow down the descent. Parachutes rely on atmospheric drag to function effectively, and without air, they would be ineffective and leave astronauts to fall uncontrollably. Instead, lunar landers are designed to use rocket propulsion for a controlled descent and landing. This method allows for precise landings on the Moon’s uneven surface.

Using Reaction Control Thrusters or Cold Gas Jets (small thrusters). The astronauts fire them in the opposite direction that the spacecraft is traveling and this thrust slows down the craft.
How do Astronauts overcome G-forces in re-entry?
Astronauts rely on the design of the spacecraft to help absorb and dissipate the G-forces experienced during re-entry. Capsules are equipped with heat shields and parachutes that slow down descent, minimizing the impact of G-forces on the astronauts inside. Additionally, astronauts undergo physical training to prepare their bodies for the stresses of re-entry.
By shutting down fuel cells what can the astronauts not do in space?
When fuel cells are shut down, astronauts cannot generate electrical power for the spacecraft, leading to a loss of energy for life support systems, communication equipment, and other critical spacecraft functions. This can impact the ability to maintain a safe and habitable environment in space.
How do spacecraft land back on earth safely?
Spacecraft land back on Earth safely by using a combination of parachutes, heat shields, and sometimes thrusters to slow down their descent. The heat shield protects the spacecraft from the intense heat generated during re-entry into Earth's atmosphere, while parachutes help to further slow down the descent before touchdown. Additionally, some spacecraft may use retro rockets or airbags to cushion the landing impact.
How did astronaut go back to the earth?
Astronauts return to Earth using a spacecraft that typically re-enters the atmosphere at high speeds. During re-entry, the spacecraft's heat shield protects it from the intense heat generated by friction with the atmosphere. Once it slows down, parachutes deploy to further reduce descent speed, allowing for a safe landing. Depending on the mission, they may land in the ocean or on solid ground.
