Far more expensive and far less productive.
Scientists continue to send astronauts to Mars for exploration and research because there is a possibility that life may exist in forms different from what the Viking probes were designed to detect. Additionally, human astronauts have the advantage of being able to explore more diverse and challenging terrains, conduct on-site experiments, and bring back samples for further analysis. Ultimately, sending humans to Mars offers a more comprehensive approach to investigating the potential for past or present life on the planet.
Do you mean Radio Telescopes? A radio telescope is a form of directional radio antenna used in radio astronomy. The same types of antennas are also used in tracking and collecting data from satellites and space probes.
Telescopes, Space missions, probes all help scientists discover more about the moon.
If by humans visiting you mean , Which planet's have had humans land on that planet the answer is none. The only other place in space that humans have visited is the moon.
Telescopes, Pictures,Satellites, and Probes
By observing them regularly using telescopes and by sending orbital or lander probes to them.
NASA occasionally sends out space probes instead of humans because astronauts could not survive on some of the places that space probes are sent to.
yes
Robot space probes and telescopes
Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.Briefly, sending probes out (for example, to get near the Sun, some planet, some comet, or some asteroid, or just to take certain measurements, like measuring the solar wind, at different distances from Earth); looking at the Universe through Earth-based telescopes; sending telescopes into orbit (where they have a clearer picture, and can see wavelengths that don't pass through Earth's atmosphere); analyzing other particles that reach Earth, such as the cosmic rays, or neutrinos.
By using robot space probes and telescopes
they use space probes,satellites,and of coarse,telescopes.
please help me answer it
Through telescopes. We have more ground based telescopes than we have instruments in space, though we have also learned a great deal through some space missions, such as through the COBE & WMAP satellites. Optical telescopes provide a wealth of information, but we can see further using radiotelescopes, and we can penetrate deeper through clouds of interstellar gas with infrared telescopes.
We use space probes, and send astronauts... etc.
Sending space probes is cheaper than sending people to other planets because space probes are typically smaller, lighter, and require less infrastructure to support life support systems and return missions. Human missions have to account for the safety, health, and well-being of the astronauts, resulting in significantly higher costs. Additionally, space probes can be designed for specific tasks and don't require return trips, whereas human missions would need to account for the return journey.
The different tools are satellites, probes, telescopes. and spacecrafts.
