NASA has reported that an engineering model of its DAVINCI descent probe passed a crucial thermal test conducted between late August and early September. To reproduce the conditions expected during the final plunge through Venus’s atmosphere, engineers placed the roughly yoga-ball-sized vessel in a ceramic-lined chamber. They raised the temperature to 465 degrees Celsius over about an hour, matching the rapid heating the probe is expected to experience before reaching the surface. The successful result indicates that the vessel can protect its scientific instruments in one of the most hostile environments explored by spacecraft. DAVINCI is designed to investigate the origin, evolution and present condition of Venus. By examining the planet’s atmosphere in exceptional detail, the mission may help scientists determine whether Earth’s neighbouring planet once had water and conditions suitable for life.

Özet ve soru Prometheus’a aittir. Haberin tamamı: NASA ↗

Beş ifade

  • descent probe: iniş probu
  • thermal test: ısıl dayanıklılık testi
  • ceramic-lined chamber: seramik kaplı test odası
  • rapid heating: hızlı ısınma
  • hostile environment: zorlu ve elverişsiz ortam

YDS mini sorusu

Why was the thermal test an important step for the DAVINCI mission?

  1. It tested the vessel’s ability to collect samples of Venus’s atmosphere during its hour inside the chamber.
  2. It reproduced the rapid heating expected during descent and showed that the vessel could shield its instruments.
  3. It established conditions under which water could have persisted, helping reconstruct the planet’s earlier habitability.
  4. It demonstrated that the probe could sustain surface operations for the period required to investigate the planet’s evolution.
  5. It identified the ceramic material needed for the probe’s outer casing by comparing its performance under Venusian heat.
Cevabı ve açıklamasını göster

Doğru cevap: B

Deneyde test kabı, Venüs’e iniş sırasında beklenen hızda yaklaşık 465 dereceye kadar ısıtıldı ve başarılı sonuç, bilimsel araçların korunabileceğini gösterdi. Bu nedenle doğru cevap B’dir.

By surviving a temperature rise that matched the expected Venus descent profile, the engineering vessel demonstrated that it could protect the probe’s instruments from extreme heat.
