How did they communicate with Apollo?
When Neil Armstrong and Buzz Aldrin stepped onto the moon in 1969, a S-Band Transponder designed and built by General Dynamics was the only communications link the Apollo 11 Astronauts had to NASA’s mission control and millions of people watching on Earth.
What technology was used on this Apollo mission?
The Apollo spacecraft required light, compact, powerful computers. So NASA and the MIT Instrumentation Lab made a daring decision. They built the Apollo Guidance Computer with a promising but relatively unproven technology: the integrated circuit, which packed multiple transistors onto a single silicon “chip.”
What programming language was used in Apollo?
assembly language
The Apollo Guidance Computer was programmed in assembly language.
What new form of technology did Apollo 15 bring to the Moon?
Changes to the Apollo spacesuit and to the portable life support system, or PLSS, were evaluated, and performance of the Lunar Roving Vehicle and the other new J-mission equipment that went with it – lunar communications relay unit, or LCRU, and the ground-controlled television assembly, or GCTA.

What was the processing power of the Apollo Guidance Computer?
But here are the basic specs: the Apollo 11 Moon landing guidance computer had a clock speed of just 1.024 MHz compared to 48 MHz for the ARM Cortex-M0 CPU in the Anker PowerPort Atom PD 2 that Heller used for his comparison.
How was Apollo 11 programmed?
The Apollo Guidance Computer (AGC) was installed on board the Apollo 11 Command Module (CM) and Lunar Module (LM). The computer’s software was written in Assembly Language (or Assembler). Assembler is considered a low-level programming language as there are very few “plain language” type words (eg.
Did the Apollo program use metric?
Contrary to urban myth, NASA did use the metric system for the Apollo Moon landings.
How do space shuttles communicate with Earth?
Spacecraft send information and pictures back to Earth using the Deep Space Network (DSN), a collection of big radio antennas. The antennas also receive details about where the spacecraft are and how they are doing. NASA also uses the DSN to send lists of instructions to the spacecraft.
How does spacecraft send data?
The Short Answer: Spacecraft send information and pictures back to Earth using the Deep Space Network (DSN), a collection of big radio antennas. The antennas also receive details about where the spacecraft are and how they are doing. NASA also uses the DSN to send lists of instructions to the spacecraft.
How did Apollo 13 communicate with Earth?
On the surface, the crew deployed a large, umbrella like S-band antenna for beaming voice and data directly back to Earth without having to relay through the CSM and its high-gain antenna array. On later missions, of course, a somewhat smaller deployable S-band antenna was carried by the Lunar Roving Vehicle.
What were two things that NASA did with their additional technology from the unused Apollo missions?

What are the input and output devices of Apollo Guidance Computer?
The AGC Had its Own Unique Display and Keyboard. To interact with the AGC, the Apollo astronauts used a display and keyboard (DSKY). The DSKY’s display used a combination of 7-segment numerical displays and indicator lights. A basic keyboard was used to enter mission programs and operations.
How many lines of code did Apollo 11 use?
145,000 lines
As an aside: Apollo 11 had 145,000 lines of code. Google has about 2 billion lines of code. Part of what makes that possible is that Google’s code is mostly written in languages like Python, not in AGC assembly language.
What measurement system is used by NASA?
Although NASA has ostensibly used the metric system since about 1990, English units linger on in much of the U.S. aerospace industry. In practice, this has meant that many missions continue to use English units, and some missions end up using both English and metric units.
Does SpaceX use metric or imperial?
Despite NASA’s non-compulsory policy, commercial space manufacturer SpaceX currently designs its systems (e.g. Dragon and Falcon 9) using metric units.
How do satellites transmit data?
Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
